Syphon Filter 3 is worth about $3-4 disc only and $12-15 brand new.
If
Syphon Filter 3 has an American Flag on it, it recently sold for $2,400 brand new. 120x more for the cover art.
Why the cover art variant so valuable and why does it exist in the first place?
Answer: 9/11
Sony was set to release Syphon Filter 3 on Sept 21, 2001. The original cover art included the US Flag and images of US Government buildings exploding. Sony had started shipping the game to retailers for the upcoming release.
After 9/11, Sony decided to delay the game and recall all shipments. Sony felt the flag cover art was inappropriate after terrorists actually targeted government buildings. Sony would change the cover art and release the game in November 2011 instead.
Most of the original shipments were returned to Sony and never made it out in the public, but some of them got out in the wild.
The 9/11 Flag variant is now extremely rare and there is an interesting story behind it. That means supply is low and demand is high (people like games with fun stories behind them), so the price for the
9/11 American Flag Syphon Filter 3 is worth 120 times as much as the regular version.
If you ever see Syphon Filter 3 in the wild, be sure to see which version it is....the flag could be worth thousands of dollars.
Thanks to an
interview from Syphon Filter 3 lead designer for information on the backstory.
